Story summary
- Italy's Giulia Schettino and Alessandro Rossi of the Italian National Research Council warn that simulations of unseen GEO debris show a chance debris could hit asteroid 99942 Apophis during its April 2029 close approach.
- A collision would create a small crater and ejecta plume while leaving the asteroid’s orbit unchanged.
- Rossi hopes the flyby will push the EU Space Surveillance System to deploy new telescopes and improve debris surveys before 2029.
